Counting using Objects
The first step in children’s number work is counting up to 10 and beyond. Children then need to understand how to relate the numbers to objects. They need to come up with a system so that they do not miss objects. We encourage children to put the objects in a line and start from one side. We also encourage them to touch the objects as they count them.

4
Relating amounts to number
Children then need to be able to recognise the numbers that they are using to count. Relating the numbers to a numeral is quite a big jump for some children. The more familiar they are with the numerals, the quicker they will learn them. = 5 = 6
5
Recognising and Writing numbers
This is how we write numbers in our school. The earlier children practise writing numbers the right way round the less likely they are to get into the habit of writing them incorrectly. In early number formation 2 and 5 are easily confused. 2 3 5 6 7 8

Place Value A child having a deep understanding of place value is integral to their progression in maths. Once they are familiar with numbers over 10 we work on identifying the ‘tens digit’ and the ‘ones’ in each number. It is important that the children know the value of each digit. In this example 13 is made up of ‘1 ten’ and ‘3 ones’ Place Value cards are one resource we use to support this concept. 3 3
9
Place Value The children need to be able to locate given numbers in a hundred square by identifying the tens digit of that number first then finding the corresponding row. They should also know that the higher the tens digit, the lower the row is located in the hundred square. Key Words: tens /units digit teens number
10
Place Value In school we also use tens rods and unit cubes to help children understand that 10 ones is the same as one set of 10. = 10 = 1 = 36 You could support this idea at home when they are counting numbers greater than 10, by grouping objects together in tens as they count up.
11
Place Value To further support this idea we have 100 squares which are the size of 10 tens rods. = 124
12
Number Facts A ‘number bond’ is two numbers which are added together to make another number. Children need to work towards a quick recall of number bonds for 5 e.g , They will also need to know the number bonds for 10 off by heart e.g , 1 + 9, etc… As their understanding of place value improves they will start to be able to recall number bonds for larger numbers using the above number bonds to help them. We do work on this in class; however once your child understands what a number bond is, quick recall comes from frequent practice. Another vital mental maths skill is doubling numbers up to 5 /10 / 20. This is first taught using hands and then pictures. After this, the children will then learn the inverse of doubling: halving.
13
Addition and Subtraction Using Objects
We often get asked what objects children should use to help them add up at home ANYTHING!!! For addition, ask children to count out two groups of objects, combine them and see how much there is ‘altogether’. For subtraction, encourage children to count out the larger group then ‘take away’ the smaller number and see ‘how many are left’. We use lots of different words for addition and subtraction, and we do not introduce the + and – symbols until children are very confident with the operations.
14
Using a number line to add
Children can start to use a number line for addition and subtraction when they start to have a better understanding of abstract number. It is important that they relate addition to ‘counting on’ and subtraction to ‘counting back’ on the number lines. They must understand that, with addition, the total amount will be the largest and, when taking away, the result will be smaller than the initial amount. =
15
Addition in year two In year two, the children will use their knowledge of place value to help with calculating addition problems. Here is an example: = First they will partition the tens and calculate. Then they partition the units and calculate. Finally the totals are recombined to find the final answer. TU TU = = 25
16
Using a number line to subtract
20 – 8 = When subtracting, children will need to understand that they can start with the largest number and count back. We also learn to ‘find the difference’ to solve subtraction number sentences, where they start with the lower number. 12 jumps
17
A hundred square When dealing with larger numbers children progress from using a number line to a hundred square. The methods of addition and subtraction are the same as on a number line. Children soon learn that, to add 10, they can simply ‘jump down’ 1 place. Aside from addition and subtraction, we use hundred square to spot the patterns in number sequences.
18
Multiplication and Division
We do not use the symbols for multiplication or division until children are confident with the concept of ‘lots of’ as repeated addition and division as ‘sharing’. Key Words: Lots of ... Sets of … Groups of … Shared between… 4 lots of 2 = 8 6 shared by 3
19
New National Curriculum
The new National Curriculum states that, by the end of year two, pupils should know how to: Recall and use multiplication and division facts for the 2, 5 and 10 times tables.
20
Word problems Once the children are confident with using the methods of each operation we use word problems so they can apply their skills to ‘real life’ situations. The problem: Bob had 24 sweets. He ate 6 sweets. How many sweets does Bob have left? What do I need to do? (take away) Write the number sentence and solve it: 24 – 6 = My answer: When the children are familiar with more than one operation (e.g. addition and subtraction), an important part of word problems is deciding what operation to use.

Other Maths in The Infants
Time Begin by sequencing events. Distinguish between times of day, e.g. morning, afternoon, night. Learn days, then months, in order. Analogue clock to tell the time. Events that happen at o’clock times. Hour hand points to an o’clock, or tells us where we are in relation to an o’clock. Minute hand tells us if it is o’clock now, or how many minutes past an o’clock or coming up to an o’clock. Once confident, move onto 12 hour digital.
26
Money Need to recognise coins and know the value of each.
When counting small amounts, tap the coin the correct amount of times. Making totals, first with 1ps, then using other coins. Adding and subtracting amounts. Finding change. The more opportunity your child has to use money, the easier they will find maths related to it.
27
Language in Maths Please see the vocabulary lists below, to show words used in maths lessons in the infants. We encourage children to verbalise their understanding and explain how they have got their answer. Talking about maths reinforces the children’s understanding and allows us to find any misconceptions they may have.
28
Key Vocabulary in Mathematics
Number Operations There are four operations, sometimes called the four rules of number and each is represented by a sign. + Addition - Subtraction x Multiplication ÷ Division Add Plus Count on Total Altogether More of Sum of Take away Count back Less Difference of Subtract Fewer Lots of Sets of Groups of Product Times Share Divide Split between
